A DUI defense attorney in southern California can help you defend your rights in a DUI case. Unlike a general attorney, a DUI defense attorney like Dan E. Chambers has specific experience in the technical aspects of DUI cases and knows how to successfully challenge the accuracy of field sobriety tests, blood tests, and breathalyzer tests through the use of hard evidence and expert witnesses. If the evidence against you is very strong, your attorney can still help by negotiating reduced penalties and sentences.
